Rafael Espindola 4e7212177f Fix for PR23310: llvm-dis crashes when trying to upgrade an intrinsic.
When trying to upgrade @llvm.x86.sse2.psrl.dq while parsing a module,
BitcodeReader adds the function to its worklist twice, resulting in a
crash when accessing it the second time.

This patch replaces the worklist vector by a map.

Leny Kholodov bebb27b0d2 [Support] Lazy load of dbghlp.dll on Windows
This patch changes linkage with dbghlp.dll for clang from static (at load time)
to on demand (at the first use of required functions). Clang uses dbghlp.dll
only in minor use-cases. First of all in case of crash and in case of plugin load.
The dbghlp.dll library can be absent on system. In this case clang will fail
to load. With lazy load of dbghlp.dll clang can work even if dbghlp.dll
is not available.

Ben Langmuir a525400d37 [Modules] Be consistent about finding a module for framework headers
We use findModuleForHeader() in several places, but in header search we
were not calling it when a framework module didn't show up with the
expected name, which would then lead to unexpected non-modular includes.
Now we will find the module unconditionally for frameworks.  For regular
frameworks, we use the spelling of the module name from the module map
file, and for inferred ones we use the canonical directory name.

In the future we might want to lock down framework modules sufficiently
that these name mismatches cannot happen.

Pawel Bylica c52eabb285 Reapply r240291: Fix shl folding in DAG combiner.
The code responsible for shl folding in the DAGCombiner was assuming incorrectly that all constants are less than 64 bits. This patch simply changes the way values are compared.

It has been reverted previously because of some problems with comparing APInt with raw uint64_t. That has been fixed/changed with r241204.

David Majnemer 1023668bc2 [MS ABI] nullptr data member ptrs are mangled differently for classes vs fns
It turns out that nullptr pointers to data members act differently in
function templates vs class templates.  Class templates use a variable
width representation proportional to the number of fields needed to
materialize it.  Function templates always use a single '0' template
parameter.  However, using '0' all the time is problematic if the class
uses single or multiple inheritance.  In those cases, use -1.

Charlie Turner 0912de3216 [GraphWriter] Don't wait on xdg-open when not on Apple.
By default, the GraphWriter code assumes that the generic file open
program (`open` on Apple, `xdg-open` on other systems) can wait on the
forked proces to complete. When the fork ends, the code would delete
the temporary dot files created, and return.

On GNU/Linux, the xdg-open program does not have a "wait for your fork
to complete before dying" option. So the behaviour was that xdg-open
would launch a process, quickly die itself, and then the GraphWriter
code would think its OK to quickly delete all the temporary files.
Once the temporary files were deleted, the dot viewers would get very
upset, and often give you weird errors.

This change only waits on the generic open program on Apple platforms.
Elsewhere, we don't wait on the process, and hence we don't try and
clean up the temporary files.

Ted Kremenek 2b41771909 Parse 'technical term' format specifier.
Objective-C format strings now support modifier flags
that can be attached to a '@' conversion.  Currently
the only one supported, as of iOS 9 and OS X 10.11,
is the new "technical term", denoted by the flag "tt",
for example:

  %[tt]@

instead of just:

  %@

The 'tt' stands for "technical term", which is used
by the string-localization facilities on Darwin to
add the appropriate spacing or quotation depending
the language locale.

Implements <rdar://problem/20374720>.

Rui Ueyama 85225b0a36 COFF: Infer entry point as early as possible, but not too early.
On Windows, we have four different main functions, {w,}{main,WinMain}.
The linker has to choose a corresponding entry point function among
{w,}{main,WinMain}CRTStartup. These entry point functions are defined
in the standard library. The linker resolves one of them by looking at
which main function is defined and adding a corresponding undefined
symbol to the symbol table.

Object files containing entry point functions conflicts each other.
For example, we cannot resolve both mainCRTStartup and WinMainCRTStartup
because other symbols defined in the files conflict.

Previously, we inferred CRT function name at the very end of name
resolution. I found that that is sometimes too late. If the linker
already linked one of these four archive member objects, it's too late
to change the decision.

The right thing to do here is to infer entry point name after adding
all symbols from command line files and before adding any other files
(which are specified by directive sections). This patch does that.
